National Standard Stainless Steel Mesh Cable Tray

Stainless steel mesh cable trays are constructed from AISI 304 or 316 stainless steel, comply with NEMA VE 1 and VE 2 standards, and are designed for high load capacity, corrosion resistance, and flexible cable routing.Material and ConstructionStainless steel mesh cable trays are typically made from AISI Type 304 or 316 stainless steel for side rails and rungs, with Type 316 welding wire used for transverse members or corrugated bottoms. All hardware, including bolts, nuts, and washers, is also AISI Type 316 stainless steel to ensure corrosion resistance and durability in harsh environments . Units are fabricated with rounded edges and smooth surfaces to prevent cable damage .Tray Types and DimensionsMesh cable trays are available in multiple types depending on application and cable quantity. Standard rung spacing is 6, 9, or 12 inches, with radiused fittings typically using a 9-inch spacing measured at the tray center . Tray widths range from 6 to 36 inches, and loading depths are 3, 4, or 5 inches per NEMA VE 1 specifications . Straight sections are supplied in standard lengths of 10, 12, 20, or 24 feet (3–6 meters), .Load CapacityEach rung is designed to support a 200 lb concentrated load at the center with a safety factor of 1.5, ensuring robust performance for heavy cable installations . Splice plates are high-strength steel, secured with 8 nuts and bolts per plate, and fixed splice connections have a maximum resistance of 0.00033 ohm .Standards ComplianceStainless steel mesh cable trays conform to the following standards:NEMA VE 1: Manufacturing requirements for metal cable trays, including ladder, wire mesh, solid bottom, and ventilated types .NEMA VE 2: Installation guidelines for metal cable tray systems .UL 568: Performance requirements for safe application of fiberglass and metal cable trays .CSA C22.2 No. 126.1: Harmonized Canadian standard for metal cable trays .IEC 61537: International standard for metal and nonmetal cable tray systems .Environmental and Operational ConditionsMesh cable trays are suitable for ambient temperatures from -20°C to +120°C, providing good ventilation and flexibility for bends, branches, and exits . The mesh design allows easy cable insertion and removal in multiple directions, supporting both power and control cables .Installation NotesTrays should be installed according to NEMA VE 2 guidelines .The mesh design allows for simple creation of bends, branches, and exits.Proper hardware and splice plates must be used to maintain structural integrity and electrical continuity . These specifications ensure that stainless steel mesh cable trays provide durable, corrosion-resistant, and flexible cable management suitable for industrial, commercial, and outdoor applications.
